Thy next foe is... A giant canopy soars to the heavens... The anger of the sleeping giant shatters the earth...
~ Dormin

The Third Colossus, nicknamed Gaius, is a major antagonist from the video game Shadow of the Colossus. It is the third boss encountered in the game and a vessel for the essence of Dormin.



Gaius and the other fifteen Colossi were created by Lord Emon to contain the fragmented essence of the defeated evil Dormin. He set them all to wander the Forbidden Lands, destroying anyone who comes their way, so that Dormin could never be resurrected.

Shadow of the Colossus

When a young man named Wander trespasses in the Forbidden Lands and asks the disembodied spirit of Dormin to resurrect his deceased lover Mono, Dormin agrees under the condition that Wander kills all of the sixteen colossi (tricking Wander into releasing his essence so he may be reborn). Wander agrees, and sets off.

Gaius is the third colossus that he encounters, sleeping on a raised platform in a secluded lake in the mountains. It will rise when Wander approaches and will immediately attack by attempting to step on Wander or slam him with its giant stone sword. Wander must make his way to a raised stone base and trick Gaius into slamming its sword into it, shattering the colossus' wrist guard and allowing Wander to scale the blade and climb onto the beast. Gaius will then try to shake Wander off as he makes his way to the colossus' stomach and head (and back of left arm in Hard Mode), stabbing its vitals. Once all vitals have been stabbed, Gaius will die, collapsing to the ground, and releasing the fragmented essence of Dormin contained within its body.

This fragmental part of Dormin will bring Wander back to the Shrine of Worship, where he will be prepared to face his next foe. It will later combine with the other fifteen parts to form Dormin, who will possess Wander and later be banished by Lord Emon.

Gaius' corpse can be seen as the credits roll.





  • Gaius and Quadratus appeared as a costume in the Shadow of the Colossus pack for the game Little Big Planet 3.
  • Excluding the ones who use projectiles, Gaius has the longest reach of any of the colossi due to the length of its sword.
  • In the Playstation 4 remake, a gold trophy called "Resist the Wrist" can be achieved by defeating Gaius without breaking its wrist guard.
